I am a newbie to this area. I just wanted to make a chat engine available within our company premises to a few users. I downloaded wildfire as the chat server and spark as the client. I installed both of them in my machine and was able to login using the spark in my machine. However when I tried to install the client in my colleagues machine, it wasnt able to login to the server running in my machine. What could have gone wrong? please help. Could it have anything to do with domain names?
